Study Notes
Programming Problem Solving
- Programming is a problem-solving process
- Programmers use programming languages to write instructions for the computer
- These instructions are then converted into a machine language format that the computer can execute
Algorithm
- An algorithm is a step-by-step procedure to solve a problem
- Helps make the whole procedure more efficient and consistent
- Identifies decision points, processes, and essential variables
- Helps identify errors in a particular process
Pseudocode
- A description of an algorithm using a natural language
- Uses short English-like statements
- Allows programmers to write codes for programs before using a specific language
Flowchart
- A diagram representing the logical sequence of steps or operations to be performed
- Uses different symbols to represent various procedural steps
Flowchart Symbols
- Terminator: Used to declare the beginning and end of the flowchart
- Input/Output: Used for user input or program output
- Process: Used to process data, usually with mathematical symbols
- Decision: Represents a comparison using logical or relational operators
- On-page Connector: Connects flowcharts on the same page
- Off-page Connector: Connects flowcharts on different pages
- Arrows: Declare the flow of the process
Rectangle Area Algorithm
- Algorithm:
- Input the width and length
- Calculate the area by multiplying length and width
- Print the area
Length Conversion Algorithm
- Algorithm:
- Input the length in feet (Lft)
- Calculate the length in centimeters (Lcm) by multiplying Lft by 30.48
- Print the length in centimeters (Lcm)
Monthly Paycheck Algorithm
- Algorithm:
- Get the base salary
- Get the number of years of service
- Calculate the bonus based on years of service:
- If (noofyearsofservice is less than or equal to two) Bonus = 300 * noofyearsofservice
- Otherwise Bonus = 500 * noofyearsofservice
- Calculate the paycheck: Paycheck = base salary + bonus
